This repository contains code and data for analyzing Reddit comments across multiple cities using LLMs (Llama 3.2 and Qwen 2.5) for classification and mitigation.

Data Collection

1. Reddit Data Collection

Run the following script to collect Reddit data:

python scripts/get_reddit_data.py

Note: You'll need to:

  • Replace CLIENT_ID, CLIENT_SECRET, and USER_AGENT with your Reddit API credentials
  • Specify your target subreddit name
  • The script outputs 3 CSVs in data/<city>/reddit/:
    • all_comments.csv (not included due to identifiable information)
    • filtered_comments.csv (not included due to identifiable information)
    • statistics.csv (included)

After data collection, run:

python scripts/random_reddit_sample.py

This generates a random set of 50 Reddit comments per city.

2. Deidentified Data

The deidentified dataset (500 comments total, 50 from each of 10 cities) is available at: output/sampled_reddit_comments_by_city_deidentified.csv

To generate this yourself:

python scripts/deidentify_comments.py
